CHARLES WILLIAM GOLBERT, OF FULTON, OKLAHOMA.

STAKING-TOOL.

Specification of Letters Patent.

Patented Feb. 1 1, 1 90s.

Application filed October 23. 1907. Serial No. 398.764.

To all whom it may concern:

Be it known that I, CHARLES WILLIAM COLBERT, a citizen of the United States, residing at Fulton, in the county of Beaver and State of Oklahoma, have invented certain new and useful Improvements in Staking- Tools, of which the following is a specification.

This invention is a staking-tool, and has for its object to provide a simple and easily operated tool of this kind having a series of punches and cooperating dies which are carried by a revolving frame, and means where by any one of the punches and dies may be readily brought into operative position.

The invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation. Fig. 2 is a horizontal section on the line 22 of Fig. 1. Fig. 3 is a vertical section. Fig. 4 is a horizontal section on the line 14 of Fig. 1.

Referring specifically to the drawings, 5 denotes the base of the machine on top of which is secured a circular block 6. From the center of this block rises a spindle 7 which supports a rotatable die-carrier 8 and a rotatable head 9 carrying the punches 10. The die-carrier is a disk provided onits upper face with a series of different dies 11 and graduated holes 12 arranged in a circle adjacent the edge of the disk. The punchcarrier has near its edge a circular series of holes in which are mounted to slide up and down therein the punches 10. Between the die and punch-carriers, inside the circle of punches, is a disk 13 which is secured to an angular block 14 mounted on the spindle 7 between the die and punch-carriers. Above the disk 13, the punches are fitted with collars 15 which are in,sliding contact with the upper face of the disk at its edge.

In the edge of the disk 13 is a recess 16 and adjacent sald recess are inclines 17 and 18 respectively. .The incline 17 leads to one side of the recess, and the incline 18 leads from the other side of the recess to the u per face of the disk. The recess and the inc ines are in the path of the collars 15 and they are for a purpose to be hereinafter described. The disk 13 is made of sheet metal, and the inclines are formed by slitting the same and bending one of the tongues thus formed upwardly from the disk to form the incline 17. The other tongue is bent downwardlyfrom the disk to form the incline 18.

On the base 5 is mounted a post 19 on which is fulcrumed a hand-lever 20 for operating the punches. The lever is held normally elevated by a spring 21 connected at its ends to the rear end of the lever and to the post 19, respectively.

The spindle 7 projects above the upper face of the punch-carrier and is fitted with a carn-lever 2iengageable with said carrier for locking the die and punch-carriers against rotation after the desired punch has been placed in operative position.

In use, the punch-carrier 9 is rotated until the desired punch is on the incline 17. This elevates the punch sufliciently to enable the work to be placed in position. The diecarrier 8 is now rotated until the desired die is directly under the selected punch, and after the work is placed in position the punch is forced down on it by the hand-lever 20. The tongue forming the incline 17 is sufliciently resilient to enable the punch to be pressed down on the work as stated and the punch will also be elevated by the tongue when the hand-lever is released thus placing the punch in position for another stroke.

If the punch is to be operated by a hammer, the die to be used is positioned under the recess 16 and the punch-carrier is rotated until the collar 15 on the desired punch clears the incline 17 and drops through the recess, whereupon the punch drops down on the (lie. The punch is then raised sufliciently to place the work in osition after which the punch is ready for a low from the hammer. the hand-lever or the hammer, the die and punclrcarriers will be locked against rotation y the cam-clamp 22. Upon rotating the punch-carrier to change from one punch to another the punches drop when the collars thereon reach the recess, 16 and then ride up the incline 18 back to the upper face of the disk 13 The periphery of the punch-carrier may be indexed so that the desired punch can be readily located. In the edges of the block 6 and the die-carrier 8 are recesses 23 and 24, respectively, which are in line with the punches, and which when they are brought together to register, enable the punches to be removed from the punch-carrier.

The tool herein described afiords a handy and convenient support for a large variety of punches and dies, it is simple in construction, and the change from one punch and die to another .can be readily made. The tool Before operating the punch by is especially designed for ewelers, the graduated holes 12 being for staff-work. The tool can also be used by blacksmiths, in this case the punch-carriers bein provided with square holes to receive d chisels and punches of various kinds.

The block 14 does not rotate on the spindle 7, the latter having a vertical slot throu h which passes a screw 26 mounted in the block. The slot permits the block to slide on the spindle so that the die and punch-carriers may be clamped by the cam 22 as heretofore described.

I claim 1. A staking-tool comprising a rotatable head, a series of punches carried thereby, a work-su port, a disk betweenthe head and the worlE-support and having a recess in its edge, collars on the punches in sliding contact with the disk, and opposite inclines adjacent the recess and in the path of the disks.

2. A staking-tool comprising a rotatable die-carrier, a rotatable head, a series of punches carriedthereby, a disk-between the die-carrier and the head and having a recess in its edge, collars on the unches in sliding contact with the disk, ELIIC opposite inclines adjlacent the recess and in the path of the dis 3. A staking-tool comprising a work-support, a rotatable head, a series of punches carried thereby, a disk between the head and the Work-support and having a recess in its edge, collars on the punches in sliding contact with the disk,'an incline leading to one side of the recess, and an incline leadin from the other side of the recess to the dislr, the recess in the disk and the inclines being in the path of the collars.

4. A staking-tool comprising a Work-support,'a rotatable head, a series of punches carried thereby, a disk between the head and the work-support and having a recess in its edge, collars on the punches, and a springtongue adjacent the recess and in the path of the collars.

5. A stakingtool comprising a base, a spindle rising therefrom, a rotatable worksupport on the spindle, a block on the spindle above the work-support, a rotatable punchcarrier on the spindle above the block, and means for locking the punch and the Worksupport against rotation.

In testimony whereof I aflix my signature, in presence of two witnesses.

CHARLES WILLIAM COLBER'I.
